APPARATUS FOR HAKING AND FILLING CHOCOLATE TUBES.

Application filed December-5, 1923i Serial No. 678,723.

This invention relates to the confectionery art, and particularly has reference to apparatus for making chocolate forms and various confectionery compounds, and the apparatus herein disclosed is an improvement on my structure made the subject of my application Serial Number 651,908, filed July 16,1923.

As disclosed in my aforesaid application, I havediscovered that chocolate and compounds thereof can be shaped, molded and formed by pressure into hollow cylinders,

and various other forms and shapes, while the same is cold orat a temperature below the melting point of thesubstance; and in my said application I have disclosed a method and an apparatus by-which these desirlscfle results canbe produced.

forniation of a chocolate tube, contem lates a suitab esubstance such as sugar or comwherein:

ound thereof with cream, siyru or flavormg matter, produced in a ui or plastic form and introduced into the tube at the place and time of its formation, which formation is according to the disclosure of my aforesaid ap lication.

In view 0 the foregoing, it is among the objects of my invention to provide a simple, economical apparatus by means of which hollow chocolate forms may be produced as a covering, sheathing, container or holder for various forms and kinds of confections, the latter being driven, forced or injected into the form simultaneously with the formation of the latter. It is also an object of my invention to produce indefinitely and by pressure a hollowcylinder of chocolate while the substance of the latter is at a temperature below its melting point and to simultaneously fill said cylinder with any desired kind'of sweetened substance,.thus producinga confection of desirable quality with facility and rapidity. a order that my invention may be clearly understood, I have provided drawings Figure lis a view showing my apparatus in longitudinal, 'vertical, central section, a few of the parts being shown in elevation; Figure2 is an enlarged view showin part of m apparatus in section substantia the line 2--2 ofFigure 1;

Figure 5 is an enlarged, central, sectional view of the core and mold of my apparatus, the view also illustrating the mode of treatment of the substances to produce a confection according to my invention;

Figure 6 is a rear endwiew of the separ rator and core of my apparatus shown in' Figure 1, the view being on a scale larger than that of Figure 1; and

Figure 7 is a perspective view of asection of the product taken substantially on the line 7-7, Figure 5.

Referring to the drawings, the numeral 1 indicates llnearly the base affording a, platform or support for the apparatus. This base has erected thereon a frame 2 which may be bolted in place, as at 3, the frame being in the form of a yoke adapted to re-,

ceive between its branches a receptacle .5

lid 6, through which opening the receptacle may. be filled with cracked ice. Passmg at the top covered by a throu h both the branches of the frame and also t rough the receptacle 5 is a cylindrical container or holder 7 adapted to receive the chocolate orsubstance in any form, the said holder being held in place by the screw-cap and bearing 8 andthe mold. 9, the cap and mold being screwed upon opposite ends of the holder 7 until they abut against the Ol1bside of the opposite branches of the frame 2.

A piston 10 operates within the holder 7, and its rod '11 is screw-threaded and extends throu h the nipple 12 operating in the bearing 0 the cap 8, said nipple having a reduced, screwthreaded end 13 upon which the handle 14'is mounted. The'bearing of the screw-cap 8, has a pin 8 which operates in a groove 12' of the nipple 12, sothat as the handle 14 is rotated the nipple may be rotated without longitudinal movement to drive the screw 11 and piston 10 lengthwlse. A gasket or washer 15 aids in sealing the outer end of the holder. At one end of the holder 7 and within the mold 9-a se arator 16 is held between the end-of the hol er and a shoulder of the mold 9, said separator being in the form of a rin 'provi ed with a plurality of arms 17, see 'gures 1, 2 and 6,

which support centrally within the iing and centrally of the holder and of the molda tubular, cylindrical core 18. This core, at its inner end within the holder, is given the form of a cone 19, orit may be given a form corresponding to the passages through the ring lfi'between the arms 17. The tubular core 18 is terminated abruptly at the outer endor nozzle 20 of the mold 9, see Figures 1 and 5, and said outer end of the core is preferably flared or beveled internally, as

, at 21. As shown in Figures 1 and 5, the

mold 9 consists of the cylindrical portion22 corresponding with the inner surface of the 24 extending at a right-angle through one of the arms 17 ofthe ring 16, to the circumference of the latter, where it coincides with a passage 25 through the mold 9, which pas-' sage 25 is enlarged to receive the tubular pipe 26, which is threaded into the said enlargement, and which pipe is jointed by an adjustable coupling 27 with a pipe 28 threaded into the conical bottom 29 of the cylindrical container 30 adapted to receivethe plastic orlimpid substance with which the chocolate cylinder is filled. The container is provided with any suitable form of closure 31 so constructed that it may be removed and provided with bolts and winged nuts 32vfor securingit in place. ,The container 30 istapped at any suitable point in its circumference adjacent the top thereof and provided with a compressed air pipe 33, which is extended to and tapped into the end of a cylinder 34, in which works a piston 35, the rod 36 of which is connected by a pitman 37 coupled to the crank 38 of a driving means] 39, it bein understood that the compressed air cylin er 34 and the mechanism shown for actuating the piston thereof are only suggestive of a means for forcing compressed air into the top of the container 30v and are not to he -taken as a limitation of my invention inithis connection. An suitable source of compressedair may e em ployed in order'to createsufiicient pressure wt in the container 30 above the confection, of whatever nature it may be, to force the latter downwardly through the conduits 28 and 26 through the tubular core 18, and into the chocolate cylinder, while theplattei is being'wrou ht 1nto shape.

' .Viewin igures 2 to 6,- inclusive, it will be seen t at the arms '17 of the separator are acutely oval incross-section, this being for the purpose of allowing free passage of the chocolate substance past the same and thrdugh the dpenings40 between said arms,

the shape given said arnis 17 facilitating the passage of the chocolatesubstance and presenting little or no resistance to such passage. The arm of the separator through which the-passage 24 is formed is slightly larger than the other arms, this being merely to accommodate the passage, which may be" of any diameter desired. As shown in Figures 1, 3 and 5, the circumferential speck 41 between the core 18 and the interior surface of the nozzle 20 is comparatively narrow, and this narrow passage predetermines the'thickness of .the shell of the chocolate cylinder; and the nozzle which is extended as shown helps to form and maintain the form of the cylinder as the chocolate sub-- stance is pressed therethrough and around the core 18. The end 21 of the core; which is beveled or flared as shown in Figures 1 and 5, enables the compressed substance forced from the container 30 to slightly ex:

pand into the chocolate cylinder; While the space 41 is shown comparatively narrow, its size can be regulated or controlled by a nozzle 20 of dilferent internal diameter, or by a core 18 of difi'erent diameter, it being'understood that a mold of different size or a separator of different size can be substituted for the ones shown; and such mold and separator may'also be given a different formm cross-sectionand at the delivery end.

The limpid or plastic condition of the substance used as a filler for the chocolate cylinder' obviates the necessity for a high de'- gree of pressure upon the top of the mass in the container 30, the pressure of the air within the receptacle being required to be suflicient only to keep the mass in motion, which latter is aided by gravity, during the passage of the mass through the conduitand the hollow" core '18.

As shown in Figure 5, the chocolate cylinder 42 with its filling 43 may be fed from the apparatusindefinitely, and in order to receive the filled cylinder and temporarily support the same and cut the product into a desired length as a preliminary to wrapping, I may couple with the apparatus shown in the drawn s'a mechanism for re- 'ceiving, holding an cutting theproduct such as isfshown in my aforesaid application; but, this entire mechanism may be eliminated and a mere table or support 42' "arranged ad]a cent the delivery en of the mold to receive and sustain temporarily the filled cylinder or .product. While on'said support the r'oduct may be chopped or cut into definite engths such as shown in Figure 7, andsubsequentlylwrapped. The container-30 may be filled with any suitable con-' fection substance, as heretofore noted, and the holder 7 may be filled (by opening the closure means atone end thereof) with chocolate in granular, shaved or other form, and

I ure 7.

formed the receptacle 5 may be filled with ice through the -door- 6, this maintaining the chocolate in the'holder 7 at a low temperature, or at a temperature below its melting point; The pumping apparatus may then be set in operation to cause compressed air to impose pressure upon the .top of the mass in the container 30, and simultaneously the piston 10 may be forced by the screw-rod. 11 lengthwise of the holder 7 to compress the contents thereof and force it into themoldend of the apparatus. This will cause the chocolate mass to form into a cylinder in the nozzle 20 of the mold around the hollow core 18, which mass will be forced from the mold atthe delivery end upon the support 42. Simultaneously therewith the filling material will flow from the delivery end of the core into the chocolate cylinder filling the same substantially as shown in Figure 5,'and producing the product shown in Fig- As before stated, the product may be in indefinitelengt-hs'or it may be cut or chopped by suitable means into definite lengths;

In the operation of the machine it is intended that the rate of delivery of the chocolate tube, and the rate at which the filler therefor is supplied to-said tube shall coordinate. In starting the machine it is recommended that, as the chocolate tube emerges, a cork or closure means be introduced therein against which the terial ma impinge causin the same to expand an fill the tube as lndicated in Figure 5."

It is within the scope of my invention'to' consider the chocolate holder as comprising filling maparts at a right-angle to the longitudinal axis of said holder, since said conduit may pass through the holder at any desired an gle and from any desired point thereo Having thus described my invention, what I claim and desire to secure by Letters Patent is: I

In an apparatus of the character described, a core forming nozzle, a supply chamber communicating with said nozzle and adapted to contain core forming materialfa tubular envelope forming opening surrounding the core' forming nozzle, :1 compression cylinder communicating with said opening and adapted to contain chocolate in solid state, means for applying suflicient pressure to the chocolate to force it through said tubular formin opening to form the chocolate into a tubu ar envelope, means for refrigerating the chocolate while in the compression cylinder suificiently to preclude the heat of compression ijrom reducing the choc olate to a"plastic state while passing through the tubular opening, and means for exuding the coreforming material through the core formng nozzle into the chocolate tube thus pro need and during the formation thereof.
